It looks like "Highlight Usages in File" functionality have been merged with the new search functionality, which is a great idea. But in the process we have lost the ability to highlight all the matches in a file. And I don't care there are more than 100 matches

.
Here is a use case for this: Say you have a pretty large log file open, with one line every second for the last 7 days. You search for an error. Just looking at the marks on the right bar you will be able to visualize if the errors happened only during the last few days (towards the end of the file). And I'm sure that everyone will come up with it own use case for this.
